Concept explainers

Compton effect

The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.

Recoil Velocity

The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.

Red light of vacuum wavelength 650 nm is travelling in non-magnetic glass with refractiveindex nG = 1.50, then meets an interface with air at an angle of incidence of 75 degrees,and total internal reflection occurs.Calculate the tangential component of the wavevector kG in glass; state two conditionson the transmitted wavevector kA on the air side; and show that this leads to an evanescent wave with amplitude decaying exponentially away from the boundary.

What is the modal dispersion (time delay between the 'straight' and 'bouncing' paths) in nanoseconds for an optical fiber of length 25 km, which has a core and cladding refractive index of 1.515 and 1.442 respectively? [Answer is negative, as straight is quicker]
Very short pulses of high-intensity laserbeams are used to repair detached portions of the retina of the eye. Thebrief pulses of energy absorbed by the retina weld the detached portionsback into place. In one such procedure, a laser beam has a wavelengthof 810 nm and delivers 250 mW of power spread over a circularspot 510 mm in diameter. The vitreous humor (the transparent fluid thatfills most of the eye) has an index of refraction of 1.34. What average pressure would the pulse of the laser beam exert at normal incidence on a surface in air if the beam is fully absorbed?

In June 1985, a laser beam was sent out from the Air Force Optical Station on Maui, Hawaii, and reflected back from the shuttle Discovery as it sped by, 354 km overhead. The diameter of the central maximum of the beam at the shuttle position was said to be 9.1 m, and the beam wavelength was 550 nm. What is the effective diameter of the laser aperture at the Maui ground station? (Hint: A laser beam spreads only because of diffraction; assume a circular exit aperture.
